It connects a 5\/16-inch male flared end to a 1\/4-inch male NPTF port, bridging flare tubing systems to threaded pipe connections in a single compact fitting. Thread sizing is 1\/2-20 on the flare side and 1\/4-18 NPTF on the pipe side. The fitting is rated for service from -40 to 250 degrees F, making it suitable for refrigerant, fuel, and hydraulic line work. Plumbers, HVAC technicians, and refrigeration mechanics typically install this type of adapter when joining flare tubing to a threaded component or manifold port.\u003c\/p\u003e\n\u003cp\u003eThis adapter is appropriate for residential and light commercial applications wherever a SAE 45-degree flare tubing run must terminate at a male NPTF fitting. It is compatible with copper, brass, aluminum, and steel tubing. Typical install scenarios include refrigerant line connections, fuel delivery systems, and hydraulic circuits that require a transition from a flared tube end to a pipe-thread port. The compact profile  -  under 1.5 inches in overall height  -  allows installation in tight spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSAE 45-degree flare connection on one end for secure, leak-resistant tube seating\u003c\/li\u003e\n  \u003cli\u003eMale NPTF thread on the pipe side provides a pressure-tight mechanical seal without sealant tape when mated to a compatible NPTF port\u003c\/li\u003e\n  \u003cli\u003eLead-free brass construction meets lead-free compliance requirements for potable and non-potable fluid systems\u003c\/li\u003e\n  \u003cli\u003eRated from -40 to 250 degrees F for broad service range across refrigerant, fuel, and hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, brass, aluminum, and steel tubing\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions suit installations with limited clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with copper, brass, aluminum, and steel tubing in SAE 45-degree flare systems requiring a 5\/16-inch male flared by 1\/4-inch male NPTF connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers, HVAC technicians, and refrigeration mechanics. Depressurize and isolate the system fully before removing or installing any flare fitting. The flare side requires a properly flared tube end seated squarely against the fitting cone  -  do not overtighten or cross-thread the flare nut. Verify NPTF thread engagement on the pipe side is sufficient to achieve a pressure-tight seal before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 5\/16 inches (Male Flared)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inches (Male NPTF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/2-20 (flare side) x 1\/4-18 (NPTF side)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlare Angle\u003c\/strong\u003e: SAE 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tubing\u003c\/strong\u003e: Copper, Brass, Aluminum, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.55 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 704048-0504\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951945646386,"sku":"704048-0504","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9799b6dbd64792cf5171751d8e0dfea_f6089c16-1e0f-4bb4-bb5c-c473e81a7dce.jpg?v=1791741759","url":"https:\/\/voomisupply.com\/products\/midland-industries-704048-0504-flare-half-union-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
